drm/display: bridge-connector: correct CEC bridge pointers in drm_bridge_connector_init

Browse Source 
The bridge used in drm_bridge_connector_init() for CEC init does not
correctly point to the required HDMI CEC bridge, which can lead to
errors during CEC initialization.

Fixes: 65a2575a68 ("drm/display: bridge-connector: hook in CEC notifier support")
Fixes: a74288c8de ("drm/display: bridge-connector: handle CEC adapters")
